Ok I know this is a controversial topic. But I tapered and this is the longest I have been sober. But I honestly thought I was going to die if I didn't quit drinking. I have absolutely no resources (like money for rehab), plus I had a toddler to consider with no help to speak of-so I couldn't even get to a doctor. I just kept cutting my wine intake in half and adding water to it. It worked for me. I tried just abruptly stopping a year before and it was the scariest experience in the world.
However, if you have the resources and can get to a doctor or rehab... go that route. They are professionals and can give you the best advice and probably proper medication.
